  By the way, in order to prevent erroneous sorting, there is a sorting system in which indicators for displaying product sorting information are provided in the sorting shelves, and indicator lights for displaying the numbers of carts are provided at the entrance and exit of the work block. When performing sorting work based on this sorting system, in order to prevent a cart different from the cart with the number displayed on the indicator light from entering the same work block, the block passageway from the work block entrance When entering the vehicle, it is necessary to identify which carriage has entered the passage from the entrance.

  Therefore, the drawstring is provided in a state of being hung from above the entrance of the work block, and first, a start instruction is issued from the controller provided at the top of the product sorting line, and the order is determined in advance on the indicator lights at the entrance. The number of the cart is flashing. Then, when the truck with the number blinked on the indicator light enters the work block from the entrance, if the operator pulls the pull string corresponding to his truck, the indicator provided on each sorting shelf in the work block The number of sorting instructions is displayed on the display corresponding to the sorting information of the cart. When the worker completes the sorting work on all sorting shelves in accordance with the number of sorting instructions, the number of the cart is flashed on the indicator lamp provided at the exit. When the cart exits from the exit of the work block, if the operator pulls the pull string provided at the exit, the blinking display of the exit indicator light disappears and it is recognized that the cart has exited the work block. The next carriage can enter the work block.

  However, in such a system, even if an operator of a truck different from the truck whose number is displayed blinking at the entrance, even if he / she pulls a drawstring and enters the work block, he / she sorts it. The sorter information of the carts in which the indicator lamp at the entrance blinks is displayed on the display device of the shelf, and the operator performs the sort operation in accordance with the wrong sort information without noticing the error.

  Furthermore, in order to identify the cart, the operator must pull the pull string from himself and declare it when entering and leaving the work block. Both the sorting work and the work of pulling the pull string are necessary. Since nerves are used, there is a problem that the burden on the operator increases and forgets to pull the pull string.

  In order to deal with such a problem, a technique using an ID tag as in the inventions described in Patent Documents 1 to 3 is conceivable. In the inventions of Patent Documents 1 to 3, the ID tag is a sorting shelf. It is not possible to identify the carriage.

  Therefore, the present invention provides a sorting system in which a display device is provided on a plurality of sorting shelves, product sorting information is displayed on the display device, and product sorting work is performed using a cart, and the cart enters a work block.

[First Embodiment]
First, the configuration of the sorting system 1 when the order in which each carriage enters the work block is not determined in advance and the carriages enter the work block one by one will be described with reference to FIGS. 1 and 2.

  As shown in FIGS. 1 and 2, the sorting system 1 includes a hand cart 15 and first to fourth work blocks 11 to 14 as a basic configuration. The hand cart 15 is loaded with collection containers 15a and 15a, and the first to fourth work blocks 11 to 14 are moved to the first work block 11 after the worker A pushes the cart 15 into the first work block 11. 2. The route of the carriage 15 from the fourth work block 14 through the third work blocks 12 and 13 to the exit from the fourth work block 14 is in series so that it becomes U-shaped (that is, the next block after the exit of the previous block) They are arranged so that the entrances are adjacent.

  Further, a controller 50 is provided in the vicinity of the entrance of the first work block 11 where the carriage 15 first enters, and an ID writer 7 is attached to the controller 50, and writing is performed by the ID writer 7. An ID tag 8 capable of storing an identification code for identifying the carriage 15 from other carriages is attached to the carriage 15. The ID tag 8 on which a unique identification code has already been written may be attached to the carriage 15 and read by the ID writer 7. In this case, the read identification code and the destination are linked by the controller 50 and stored.

  On the other hand, the first to fourth work blocks 11 to 14 are formed by arranging a plurality of sorting shelves 9... 9, and the carts are sorted by the sorting shelves 9. There are provided number indicators 10... 10 for displaying the number of sorting to be performed. The number indicators 10... 10 display a number display section 10 a... 10 a for displaying the sorting number of the carriage 15 and the number display section 10 a... 10 a when the worker A finishes the sorting operation. And a completion button 10b for turning off the light.

  In addition, the entrance gates 16 to 16 of the first to fourth work blocks 11 to 14 are respectively provided with an entry detection unit 16a (not shown) for detecting the entry of the carriage 15 into the work block and an identification code of the carriage 15. ID readers 16b... 16b (not shown) are provided, and an entrance abnormality alarm device 16c... 16c is provided above the entrance gates 16. Further, exit gates 17 to 17 of the first to fourth work blocks 11 to 14 are provided with exit detection units 17a to 17a (not shown) for detecting the exit of the carriage 15 from the work block and exit lamps 17b to 17b. And an abnormal exit alarm device 17c... 17c are provided above the exit gates 17. The inside of the first to fourth work blocks is divided into a plurality of zones, and zone lamps 18... 18 are provided at the boundaries of the zones, above the exit gate 17 of the fourth work block 14. Is provided with a management alarm device 19.

  Next, based on the sorting system 1, the order in which the carts enter the work blocks is not determined in advance, and the carts enter the work blocks one by one in an arbitrary order and perform sorting work. It demonstrates using FIGS. 3-5. The sorting work taken up in the present embodiment is picking work, and the worker A sequentially places the carriage 15 in the first to fourth work blocks 11 to 14 along the directions indicated by arrows a to e in FIG. Let them enter, and sort them in each block.

  First, as shown in FIG. 3, the controller 50 outputs a control signal to the ID writer 7, and the ID writer 7 writes an identification code into the ID tag 8 and inputs it.

  When the carriage 15 with the ID tag 8 attached enters the first work block 11, the entry detector 16a of the entrance gate 16 of the first work block 11 detects the entry of the carriage, and the ID reader 16b Reads the identification code of the carriage 15 and outputs a signal to the controller 50. At this time, the controller 50 outputs a control signal to the number indicators 10... 10 or the entry abnormality alarm device 16c according to the input information read by the entry detection unit 16a and the ID reader 16b of the entrance gate 16.

  Next, when all the number indicators 10... 10 displayed in the first work block 11 are turned off, a signal is output to the controller 50, and the controller 50 controls the exit lamp 17b and the zone lamps 18. Output a signal. And when all the number indicators 10... 10 are not turned off, the exit detection unit 17a of the exit gate 17 of the first work block 11 detects the exit of the carriage and outputs a signal to the controller 50. The controller 50 outputs a control signal to the exit abnormality alarm device 17c.

  Next, as shown in FIGS. 4 and 5, first, in step S1, the operator A of the carriage 15 specifies sorting information such as date and shipping destination, and the process proceeds to step S2 where the ID tag 7 is moved to the carriage. 15 identification codes are written in the ID tag 8 (the identification code of the cart 15 written in advance may be read).

  In step S3, the controller 50 associates the identification code with the sorting information. Next, proceeding to step S4, the controller 50 confirms whether or not the carriage 15 has arrived at the entrance gate 16, and if it is confirmed that it has arrived at the entrance gate 16 (YES), the next step S5 is performed. If it has not arrived (NO), the process returns to step S4 again to check whether the carriage 15 has arrived at the entrance gate 16 or not.

  When the carriage 15 arrives at the entrance gate 16, the process proceeds to step S5, where the ID reader 16b of the entrance gate 16 reads the identification code of the carriage 15. When the identification code of the carriage 15 is read, the identification code is sent to the controller 50, and the process proceeds to the next step S6, where the controller 50 determines whether there is sorting information associated with the identification code. Judgment is made.

  As a result of the determination, if there is no sorting information associated with the identification code (NO), in step S7, after the entry abnormality alarm device 16c issues an alarm, the process returns to step S4, and the carriage 15 is added to the entrance gate 16. Check if has arrived. If there is sorting information associated with the identification code (YES), the process proceeds to the next step S8, and the controller 50 sets the sorting number in the number indicators 10 ... 10 in the work block corresponding to the sorting information. indicate.

  Next, proceeding to step S9, the controller 50 sets the exit lamp 17e in the exit prohibition mode and prohibits the carriage 15 from exiting the work block. Then, the worker A performs a sorting operation according to the sorting number displayed on the number display 10... 10 in the work block. At this time, when the sorting operation is finished for the products displayed by one number display 10, the sorting operation for the products is completed by pressing the completion button 10b of the number display 10 to turn off the display. .

  In step S10, the controller 50 determines whether or not the completion button has been pressed. If the completion button has not been pressed (NO), the process returns to step S10 and the completion button has been pressed ( YES), the process proceeds to the next step S11, where the controller 50 turns off the number display on the number display 10.

  Next, it progresses to step S12 and the controller 50 determines whether the trolley | bogie 15 has complete | finished all the sorting. When all the sorting is not completed (NO), the process proceeds to step S13, and the controller 50 determines whether the carriage 15 has arrived at the exit gate 17 of the work block. If the carriage 15 has arrived at the exit gate 17 (YES), in step S14, the exit abnormality alarm device 17c issues an alarm and then returns to step S10 to determine whether or not the completion button 10b has been pressed. . And also when the trolley | bogie 15 has not arrived at the exit gate 17 yet (NO), it returns to step S10 and it is determined whether the completion button 10b was pushed.

  On the other hand, if all the sorting is completed in step S12 (YES), the process proceeds to step S15, where the controller 50 allows the exit lamp 17e to be in the exit permission mode and allows the carriage 15 to exit the work block. To do. In step S16, it is determined whether or not the carriage 15 has arrived at the exit gate 17. If it has not arrived (NO), the process returns to step S16. If it has arrived (YES), the next step is performed. Proceeding to S17, the carriage 15 leaves the work block. Then, the process proceeds to step 18 where the controller 50 determines whether or not the sorting has been completed for all blocks. If the sorting of all the blocks has not been completed (NO), the process proceeds to step S19 and the cart is moved. If 15 goes to the entrance gate 16 of the next work block and the sorting of all the blocks has already been completed (YES), the sorting work is finished at that point.

  Further, after the carriage 15 enters the first work block 11 that is the first work block and exits from the exit gate 17 of the fourth work block 14 that is the last work block, the worker A ships the carriage 15. The product is inspected at the venue, and the inspected product is loaded on a truck and delivered.

  In addition, since the approach order of the carriage is not predetermined and a plurality of work blocks are arranged side by side, the controller 50 confirms whether the carriage 15 has passed all the work blocks on which the number of sorting is displayed. Do. That is, the operator A misunderstands, for example, without going through the second and third work blocks 12 and 13, immediately goes from the first work block 11 to the fourth work block 14 and exits from the fourth work block 14. When this occurs, the management alarm device 19 provided at the exit gate 17 of the fourth work block 14 issues an alarm so that the worker A can be made aware.

  Since the sorting work using the carriage 15 is performed as described above, first, when the carriage 15 is about to enter the work block, the identification code of the carriage written in the ID tag 8 of the carriage. , And the sorting number is displayed on the number indicators 10... 10 provided on the plurality of sorting shelves 9... 9 according to the read identification code of the carriage 15. Each carriage is automatically identified when entering the vehicle, so that the burden on the worker A is reduced, and the sorting operation is reliably performed according to the sorting quantity, so that the occurrence of erroneous sorting is avoided.

  When the exit detection unit 17a of the exit gate 17 of the work block detects that the carriage 15 approaches the exit gate 17 in order to exit the work block, the sorting is not yet completed in the work block. Since the warning is issued to the carriage 15 by the exit abnormality alarm device 17c, the carriage 15 is withdrawn from the work block after the worker A has completed the sorting work with certainty. It is possible to avoid the occurrence of sorting omission in the inside.

  Further, when the controller 50 confirms whether or not the cart 15 has passed all the work blocks for which the number of sorting is displayed, and issues a warning by the management alarm device 19, the cart 15 It can be monitored that the sorting work is finished without entering the work block having the sorting information, and the sorting omission can be prevented.

[Second Embodiment]
Next, the order in which each carriage enters the work block is determined in advance, and the configuration of the sorting system 2 when the carriages enter the work block one by one in accordance with the predetermined order will be described with reference to FIGS. 6 and 7. explain. In addition, the description which abbreviate | omits the part which overlaps with the sorting system 1 in which the order which the trolley | bogie mentioned above enters is not predetermined, and trolley | bogie approachs a work block one by one is abbreviate | omitted.

  First, as shown in FIGS. 6 and 7, the sorting system 2 has the same configuration as the sorting system 1, and an entrance cart is provided above the entrance gates 16 to 16 of the first to fourth work blocks 11 to 14. Number display devices 16d... 16d are provided.

  Next, the case where each carriage enters the work block one by one according to a predetermined order and performs the sorting work based on the sorting system 2 will be described with reference to FIGS.

  First, as shown in FIG. 8, the controller 50 sends a control signal to the approaching carriage number display device 16 d to display the number of the carriage 15.

  Next, as shown in FIG. 9, first, in steps S21 to S23, the same control as that in steps S1 to S3 in the first embodiment described with reference to FIG. 4 is performed. In step S23, when the controller 50 associates the identification code of the carriage 15 with the sorting information, in the next step S24, the controller 50 blinks the number of the carriage 15 on the entry carriage number display device 16d according to a predetermined entry sequence. Display. At this time, the blinking display of the approaching carriage number display device 16d indicates that the carriage 15 has not yet entered the work block.

  In steps S25 and S26, the same control as in steps S4 and S5 in the first embodiment is performed. When the ID reader 16b reads the identification code of the carriage 15 in step S26, the controller 50 collates the identification code of the carriage 15 with a predetermined entry order in the next step S27. In step S28, the controller 50 determines whether the identification code read by the ID reader 16b matches the entry order.

  As a result of the determination, if the identification code and the entry order do not match (NO), the process proceeds to step S29, the entry abnormality alarm device 16c issues an alarm, and then the process returns to step S25, where the carriage 15 enters the entrance gate 16. Judge whether or not you have arrived. If the identification code and the entry order match (YES), the process proceeds to the next step, but in the steps from the time when the carriage 15 enters the work block until the sorting work is finished, Since the same control as steps S8 to S19 in the first embodiment is performed, the description thereof is omitted.

  As described above, since the sorting work using the carriage 15 is performed, first, when the entry order of the carriage 15 to the first to fourth work blocks 11 to 14 is predetermined, The controller 50 collates the identification code of the carriage 15 read by the ID reader 16b of the entrance gate 16 of each work block with the predetermined entry order. As a result, the identification code of the carriage 15 and the predetermined entry order are determined. Since the number of sorting according to the identification code of the cart 15 is displayed on each of the number indicators 10... 10 when they match, the sorting number is displayed when the identification code of the cart 15 does not match the predetermined entry order. It is not displayed and missorting does not occur.

  Next, as a result of the verification by the controller 50, an alarm is issued when it is determined that the carriage 15 that is about to enter the work block does not match the predetermined entry order. It is possible to prevent the cart 15 that does not comply from entering the work block and to avoid the occurrence of misclassification.

  Then, since the entry truck number display device 16d of the entrance gate 16 of the work block displays the carriage number of the carriage 15 that should enter the work block next in accordance with the predetermined entry sequence, the worker A is the carriage. It is possible to know whether or not 15 can enter the work block, and the predetermined order of entry can be reliably observed, and the occurrence of erroneous sorting can be avoided.

  In addition, since a plurality of the first to fourth work blocks 11 to 14 are arranged in series, the predetermined entry sequence can be surely observed in each cart while supporting a complicated layout sorting line. This makes it possible to avoid the occurrence of incorrect sorting.

  When the first to fourth work blocks 11 to 14 are provided in series in order to deal with a complicated layout sorting line, the exit gate 17 of the previous work block and the entrance gate 16 of the subsequent work block You may make it also use.

  In this way, the first to fourth work blocks 11 to 14 are provided in series after the number of members is reduced by using both the exit gate 17 of the previous work block and the entrance gate 16 of the subsequent work block. Therefore, it is possible to deal with sorting lines with complicated layouts, and to avoid the occurrence of wrong sorting in each work block.

  Furthermore, when the exit gate 17 of the previous block and the entrance gate 16 of the subsequent block are combined as described above, when the carriage 15 moves on the boundary between the blocks, exit management from the previous block, It is possible to manage the approach to the subsequent block at the same time. On the other hand, if the dual block is not used, the exit gate 17 of the previous block and the entrance gate 16 of the subsequent block will be provided separately. The carriage 15 that has left the previous block can wait on the spot without entering the subsequent block.

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

  As described above, according to the present invention, in a sorting system in which a display is provided on a plurality of sorting shelves, product sorting information is displayed on the display, and a product is sorted using a cart, Sorting that automatically identifies each truck when entering the block, reduces the burden on the operator, and reliably avoids misclassification in sorting work, thereby improving work efficiency. It is possible to provide a system, which is widely suitable for a product sorting system in which product sorting information is displayed on a sorting shelf and an operator performs sorting work based on the displayed sorting information.
