DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited to the embodiments without departing from the spirit of the present invention.

In FIG. 1, 10 is a picking carriage, R
Is a passage of the carriage 10. 20 is a picking shelf arranged along the passage R. The ID tag 6 serving as an index indicating the address of the shelf is arranged on the side of the first row of the picking shelf 20 that is the entrance of the passage R. The transmitter / receiver 11 as a reading unit provided on the trolley 10 so as to face the ID tag 6 transmits microwaves toward the ID tag 6 and receives microwaves transmitted from the ID tag 6. It has become.

As shown in FIG. 2, the carriage 10 includes a control unit 1
2, an encoder 13 as a detection means for detecting the traveling distance, an IC card reader / writer 14, a color display 15, and a speaker 16 as a sound output means. The control unit 12 detects that the transceiver 11 has received the microwave from the ID tag 6, resets the encoder 13, and identifies the current position of the carriage 10 by the count value after the reset. The IC card reader / writer 14 reads information about picking from the IC card and outputs the read result to the control unit 12.

The control unit 12 uses the IC card reader / writer 1
Based on the information from 4, the shelf to be picked is specified, and when the trolley 10 arrives in front of the ream, the work instruction in the ream is output to the display 15 and the trolley in front of the ream to be picked. A voice signal is output to the speaker 16 so that the worker can recognize that the 10 has arrived by voice. The output from the control unit 12 causes the display 15 to display a work instruction in the series, and the speaker 16 outputs a predetermined work instruction sound.

In the present embodiment, the control unit 12 outputs not only one work station to be picked but also a work instruction of a station in the vicinity of the station to the display 15, so that the operator stops the carriage 10. You can walk to a station near the station and pick it.

The voice emitted from the speaker 16 may be a simple buzzer or a synthetic voice showing a predetermined message. The voice notification may be ended when the traveling of the carriage 10 is stopped, or may be ended in a timed manner by a timer or the like.

Next, a concrete working example will be described. (1) An IC card is received by an IC card reader / writer or the like connected to a terminal of a computer, and this is inserted into the IC card reader / writer 14 of the carriage 10.

(2) In order to start the picking work, an operation button (not shown) is operated to display the plane layout of the picking rack on the display 15, and the cart 10 is manually pushed to the picking rack to be worked.

(3) When the carriage 10 approaches the entrance of the passage R, the ID microwaves from the ID tags 6 provided in the first series of the picking shelves 20 are received by the transceiver 11.
The control unit 12 detects this and the encoder 13 is reset.

(4) As shown in FIG. 4, the picking shelf 2
Assuming that one of the picking locations at 0 is the fourth station, the control unit 12 determines that the point before the picking location, that is,
When the trolley 10 reaches a point (point X in the figure) near the boundary between the fourth station and the third station, this is detected by the count value of the encoder 13 and a picking work instruction is output to the display 15. At the same time, a voice signal is output to the speaker 16 so that the operator can recognize by voice that the trolley 10 has arrived before the train to be picked.

At this time, the display 15 has a station (fourth station) to be picked and a station (fifth station) immediately after that (fifth station).
And an elevation view, which is a layout diagram showing the line) are displayed at the same time. The example of the display screen shown in FIG. 3 is a case where the picking shelves 20 are arranged on both left and right sides of the passage R, and the picking shelves 20a and 20b on both sides are three-dimensional with the fourth and fifth stations sandwiching the carriage 10. Is displayed in.

In the elevation view of FIG. 3, picking points P1 to P4 are displayed in red so that all the frontages to be picked in the fourth and fifth trains can be distinguished from other frontages. Further, the picking points P1 to P4 display the item numbers and the planned pick numbers of the items to be taken out from the frontages. For example, the work instruction information indicated at the picking point P1 indicates that 15 items with the product number “AAAA” should be picked from the center opening of the second stage in the fourth row on the right side. It should be noted that the display color of the picking unnecessary portion in the elevation view may be different for the series where picking is required and the series where picking is not required.

As shown in the time chart of FIG. 4, since the display on the display 15 is performed from before the carriage 10 reaches the station (fourth station) where picking should be performed (point X in the figure), The worker can recognize the existence of the series before the fourth series.

In addition to the display on the display 15, voice work instructions are given from the speaker 16, so that even if the operator is pushing the trolley 10 while looking away, he or she can recognize the string to be picked. You can

(5) According to the work instruction displayed on the screen, the worker takes out the specified number of picks of the specified product number from the specified picking location (frontage) and stores them in the bucket on the trolley. At this time, the worker may carry out the picking operation in an efficient order from a plurality of frontages to be picked while the carriage 10 is stopped. If possible, the picking operations from a plurality of nearby frontages may be collectively performed.

(6) When all the picking work in the fourth and fifth stations is completed, the operator operates a completion button (not shown) provided on the carriage. When the completion button is operated, the display in the display 15 is switched to the plane layout diagram described in (2) above.

(7) Thereafter, the same operation is repeated for all the picking shelves 20 shown in the plan layout,
When all the work is completed, the carriage 10 is returned to the origin.

In the present embodiment, the elevation view in the display 15 displays the portions corresponding to all the frontages to be picked so as to be distinguishable from other locations. However, when the frontages to be picked are many. May be displayed separately.
