Abstract

PURPOSE:To facilitate searching of inventories. CONSTITUTION:An operator in a warehouse makes a bar code reader 1 read a bar code on a sheet 11 to input the ID number of a desired inventory among inventories 10a to 10f. A radio terminal 2 transmits the ID number outputted from the bar code reader 1. A reception part in each responder 3a to 3f take out the 10 number from a received magnetic wave. A control part in each of the responders signals by a buzzer when the ID number obtained by the reception part and an ID number characteristic to each inventory, which is stored in a storage part, are coincident. Thus, the desired inventory can easily be found out.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inventory item search system that facilitates the inventory item search in a flat warehouse, for example.

[0002]

2. Description of the Related Art Conventionally, in a flat warehouse in which received goods are piled up as they are
(tification) number and position information (for example, a shelf zone number) in the warehouse where the received goods are placed are input from the terminal as the location information. Then, during collection work such as warehousing or inventory, location information for each item or each shelf zone is output to a terminal screen or a form, and the collection work is performed based on this location information.

[0003]

In searching for inventory items in such a collection operation, even if the approximate location such as a shelf zone is known from the location information, the total number of inventory items that have been mixed and piled up can be visually confirmed. However, there was a problem in that it had to be searched for, which required a great deal of labor. In addition, if the location information is erroneously input, it may not be possible to search for inventory items, which causes a loss of inventory items. The present invention has been made to solve the above problems, and an object of the present invention is to provide an inventory item search system that facilitates the inventory item search.

[0004]

According to the present invention, an input device for inputting an ID number of an inventory item to be searched, a wireless terminal for transmitting an ID number output from this input device, and an inventory item are respectively provided. A unique ID number is attached to this stock item, and when the ID number transmitted from the wireless terminal matches the stored ID number, a responder that emits a response sound to notify the location is provided. is there. Also, the transponder is
A receiving unit for receiving the ID number transmitted from the wireless terminal, a storage unit that stores an ID number unique to each in-stock item, an ID number obtained by the receiving unit, and the storage unit. The control unit outputs a match detection signal when the ID numbers match, and a response sound output unit that outputs a response sound when the match detection signal is output from the control unit. Further, instead of the response sound output section, it has a light emitting section that emits light when a coincidence detection signal is output from the control section.

[0005]

According to the present invention, the wireless terminal transmits the ID number input by the input device, and the responder emits a response sound when the ID number transmitted from the wireless terminal matches the stored ID number. Emit. Further, the control unit outputs a match detection signal when the ID number received by the reception unit and the ID number stored in the storage unit match, and the response sound output unit emits a response sound by the match detection signal. . Further, the light emitting unit emits light when the coincidence detection signal is output from the control unit.

1 is a block diagram of an inventory search system showing an embodiment of the present invention, and FIG. 2 is a block diagram of a responder used in this inventory search system. In FIG. 1, reference numeral 1 is a bar code reader serving as an input device for inputting an ID number of a stock item to be searched for, and 2 is a wireless terminal for transmitting the ID number output from the bar code reader 1.

Further, 3a to 3f are stocked items 1 in a flat warehouse.
For example, it is a card-shaped transponder attached to 0a to 10f, stores an ID number unique to each stock item, and when the ID number transmitted from the wireless terminal 2 matches the stored ID number, the location is determined. A response sound is emitted to notify.

In FIG. 2, reference numeral 4 denotes a receiving section for receiving the ID number transmitted from the wireless terminal 2, which is composed of an antenna, a demodulation circuit, etc. (not shown), and 5 stores an ID number unique to each stock item. Storage unit, 6 is the ID obtained by the receiving unit 4.
When the number and the ID number stored in the storage unit 5 match, a control unit that outputs a match detection signal, and 7 becomes a response sound output unit that issues a response sound when the match detection signal is output from the control unit 6. It is a buzzer.

Next, the operation of such an inventory searching system will be described. First, the warehouse worker inputs the ID number of a desired inventory item among the inventory items 10a to 10f by causing the barcode reader 1 to read the barcode indicating the ID number printed on the sheet 11. Then, the wireless terminal 2
Modulates the ID number output from the barcode reader 1 and transmits the electromagnetic wave as a medium.

Next, the responders 3a to 3f attached to the stocked items 10a to 10f receive the electromagnetic waves transmitted from the wireless terminal 2 and judge whether or not the response is a call for a response. That is, the receiving unit 4 in each transponder demodulates the received electromagnetic wave, extracts the ID number, and outputs the ID number to the control unit 6.

Then, the control unit 6 compares the ID number obtained by the receiving unit 4 with the ID number read from the storage unit 5, and outputs a coincidence detection signal to the buzzer 7 when these coincide with each other. The buzzer 7 emits a response sound in response to the coincidence detection signal.

As described above, for example, when the user wants to find the stock item 10a, by inputting the ID number of the stock item 10a from the bar code reader 1, the responder 3a emits a response sound to inform the location thereof. Can easily find the stock 10a. Although a bar code reader is used as the input device in this embodiment, the ID numbers of stock items may be directly input using, for example, a keyboard. Further, although the buzzer 7 is used in the present embodiment, it may be replaced with a light emitting portion including a lamp or the like, and this light emitting portion emits light when the coincidence detection signal is output from the control portion 6 and its location. Let me know.

[0013]

According to the present invention, the ID of the stock item to be searched for
When you enter a number from the input device, the responder attached to the corresponding inventory item informs its location with a response sound, so you can easily find the desired inventory item and save the labor in collecting work such as shipping or inventory. It can be reduced significantly. Further, since the stocked product can be searched for without depending on the location information indicating the position of the stocked product, the stocked product is prevented from being lost due to erroneous input of the location information. Further, by configuring the transponder from the receiving unit, the storage unit, the control unit, and the response sound output unit, it is possible to realize the transponder that notifies the location of the response sound with a simple configuration. Also,
By providing the light emitting unit instead of the response sound output unit, it is possible to realize a transponder that notifies its location by light with a simple configuration.
